Which mechanism primarily sculpts ventifacts in periglacial environments?

💡 Explanation

Aeolian abrasion sculpts ventifacts because wind-driven particles impact exposed rock surfaces eroding the softer materials and facets, therefore forming a characteristic shape, rather than effects from just salt, ice, or temperature fluctuations.
